Elemental composition of sediments from a former silver mine in Freiberg/East Germany

1999

Abstract We have determined the contents of 48 elements in 11 representative sediments from a former Ag-mine in Freiberg/Sachsen. As analytical method the instrumental neutron activation analysis (INAA) was used without chemical preconcentration. Strongly varying compositions were observed for both the main and trace elements. Of particular interest were the high lanthanide and Th/U contents in these sediments.

Determination of gold in two Egyptian gold ores using instrumental neutron activation analysis

2003

Abstract The applicability of thermal neutron activation analysis for the determination of gold and other elements in two Egyptian gold ores has been studied. Ten samples collected from El Sukari and Atud in the Eastern Desert-Egypt have been analyzed. The samples were properly prepared together with their standards and simultaneously irradiated in a neutron flux of the order 7×10 11  n/cm 2  s using the TRIGA research reactor at Mainz. Short-term (1 and 5 m) irradiation in the pneumatic system was also used for detection of the elements with shorter half-lives. After activation, the samples were subjected to γ -ray spectrometry using a high-purity germanium detection system and computerize…
